Xperia Z3 is powered up with Qualcomm’s Snapdragon 801 Quad Core CPU clocked at 2.5 GHz accompanied by Adreno 330 GPU. Out of the box, Xperia Z3 runs on Android 4.4.4 KitKat.

Well, I guess that was enough to give you guys a flashback of the Xperia Z3. In case you’re planning to get your hands on this new beast by Sony, you would like to unleash the true power of your device as soon as you start exploring it. The very thing that will let you do so is the root access and to go beyond the boundaries a little further, you will need a custom recovery as well. Thanks to XDA senior member monxwho just came up with Adv Stock Kernel for the Xperia Z3 that will let you load TWRP 2.8 recovery on your device and you can root it once you have the recovery running on it. That means you won’t have to wait once you get your device, the device isn’t available around the world as yet and the recovery and root access are already available, this definitely happens to be a great development. Before you start looking out for the methods to install recovery and gain root access, we’ve already done this job for you.

As you move forward in the proceeding post, you will come across a comprehensive guide that will help you to install TWRP 2.8.0.1 recovery on your Sony Xperia Z3 D6653, D6633and D6603and you will be able to rootyour device as well. Let’s go through the instructions now and get across the wall now.

Early Preparations:

1. This is only for Sony Xperia Z3 D6653, D6633, D6603!

This guide is only for the devices mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing these files on any other device will result in bricking it so make sure that you meet this requirement first of all.

2. Battery should be charged at least over 60%.

Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.

3. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

Titanium Backup– If already rooted, use Titanium Backup to backup all of your apps, system data and other important content.

Backup Nandroid – If CWM or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.

4. Enable USB Debugging Mode on your device.

Enable USB debugging mode on your device. To do so, tap settings>developer options>USB debugging. If you can’t find developer options in settings, then tap settings > about device and tap “Build Number” for 7 times and you’ll get em’ activated under settings.

You can only flash Adv. Stock Kernel if your device has an unlocked bootloader. You can read all about unlocking your device’s bootloader and unlock it using this guide. Make sure that you do this carefully.

7. Use OEM data cable to establish connection.

Make sure that you use the phone’s original data cable to establish connection between your phone and the PC. Using a different data cable might result in interrupting the firmware installation.

Disclaimer: The methods involved in flashing custom roms and rooting your phone is highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is SONY in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.
